AI Test Generator: Turn Any Article Into a Quiz (Free)

1. Create a free account with email or Google. No credit card needed.
2. Open the quiz maker, click Generate with AI, then choose Paste text or Upload PDF.
3. Paste the article, or upload the file, set the question count and difficulty, and generate. Sheelon’s AI drafts multiple-choice, true/false, and type-answer questions grounded in what you gave it, typically in under 30 seconds.
4. Edit anything you want changed, then host it live with a join PIN, or switch to Assignment mode for self-paced homework with a deadline.

Sheelon is not the only tool that can turn an article into a test. If you are weighing options, ignore the word “AI” on its own, since every tool claims it now. Four questions decided the ranking below, because they are the differences that actually change your day-to-day:

1. Is AI on the free plan, or paywalled? A lot of tools advertise AI but only ship it to paying users. For a teacher trying a tool out, that is the whole game.
2. Can it generate from your documents? Topic prompts are fine. Generating from your own chapter or slides is better, because the questions match what you taught.
3. What question types come out? Some generators only produce multiple choice. Recall-style and interactive formats matter for learning, not just multiple choice.
4. How much editing does the output need? A generator that needs heavy rewriting is barely faster than starting from scratch. Aim for 1 to 3 small edits per 10 questions.

On sourcing: the Sheelon details come from our hands-on product work - we build it. For every other tool, we compared its published plans, limits, and AI features against its public pricing and feature pages, verified in August 2026. The one hands-on claim about competitor output is the same-prompt test below: one run each through the generators of Kahoot, Wayground and Edcafe AI (plus Sheelon, Formative and QuestionWell) in September 2026, the generator step only. Blooket and Gimkit were not run. Where output quality matters, run the 10-minute test further down on any tool you shortlist.

Pricing is the individual teacher rate, checked against each tool’s public pricing page in August 2026. The AI-on-free cells for Kahoot and Wayground are what we saw when we ran their generators on free accounts in September 2026. Competitor plans and AI features change often, so treat the table as a starting point and confirm current details on each tool’s pricing page before you commit.

On 19 and 20 September 2026 we gave six AI quiz generators the same prompt: a 10-question multiple-choice quiz on photosynthesis for grade 7 science, four options, one correct answer, testing understanding rather than recall. One run per tool. Two graders, blind to each other, judged every key and an adjudicator ruled on disputes; a script counted where the correct answer sat. Sheelon is ours and was graded the same way, on the owner’s Ultimate account. Formative ran on its trial; the other four on free plans. QuestionWell is not in the ranking above, but it ran on 20 September once a signed-in teacher account had passed its sign-in wall.

• Read every key. Formative keyed two of ten wrong: “What do plants use from sunlight to make food?” went to Chlorophyll, which the plant makes itself, and “Which of these is a raw material in photosynthesis?” went to Sunlight with neither carbon dioxide nor water on the list. QuestionWell keyed two wrong too: carbon dioxide as what a plant photosynthesizing without water would not need, and a sealed-box question that asked for a gas but offered only more-or-less changes. Sheelon had one ambiguous key, a distractor that restates the answer in looser words.
• The answer clusters in one slot. Formative put it in A on six of ten, Kahoot in B on six of nine, Edcafe in B on five of ten and Wayground in D on five of ten. Sheelon’s spread was 3/2/2/3 and QuestionWell’s 3/3/1/3.
• Weak distractors were everyone’s problem. Kahoot offered “Shelter and fur” as what photosynthesis gives animals, Wayground offered “Milk from another plant” as a plant input, and Sheelon, highest at 3.3 out of 5, still offered “They capture underground light rays” for root hairs.

Kahoot delivered nine questions, not ten: its tenth card was a poll with no correct answer that the free plan could not add. Read the full results and method in the classroom AI guide, or download the raw data (JSON): every question, both graders’ scores and the rulings.

Each entry follows the same pattern: who the tool is best for, how it handles AI generation, its honest limits, and what the free tier and paid plan give you.

Before you commit a term’s worth of prep to one tool, run this quick test on any generator you are considering:

1. Generate a 10-question quiz on a topic you know deeply.
2. Count how many questions you would actually edit. More than 3 out of 10 is a warning sign.
3. Try generating from one of your own documents, if the tool supports it, and check whether the questions match your wording.
4. Check what it costs to do this repeatedly, not just once. The free trial number matters less than the monthly reality.

Match the tool to the job in front of you:

• Generate a test from your own article or PDF, free: Sheelon. That workflow is the core of the product, and the free plan is enough to judge the output.
• Assign ready-made practice quizzes at scale: Quizizz, if the paid plan fits your budget. On Sheelon, the community library covers the same job for free, with a smaller catalog.
• A familiar live game, with AI drafting from a topic or PDF on free: Kahoot, if your students already know it and the pricing works.
• Game-format engagement from existing sets: Blooket or Gimkit, with questions you author elsewhere.
• Self-paced homework with AI drafting, no live element: Edcafe AI, with the most generous free AI allowance of the group, as long as 40 responses per activity is enough.
• Try a live quiz right now, no account: Sheelon’s free quiz games page has ready-to-host games you can start in a browser.

If the job is turning an article, chapter, or slide deck into a test with AI, Sheelon is the strongest starting point: AI generation from your own documents is on the free plan, and unlimited AI on Pro costs $39 a year. Quizizz wins on library size and self-paced practice if the $216/yr plan fits your budget, and Blooket and Gimkit win on game-format engagement once you have questions to play with.

Whichever way you lean, run the 10-minute test above before committing a term of prep to any generator. A free plan you can actually generate with is a more honest trial than a feature list. And if quizzes are one piece of a bigger prep problem, our roundup of best AI tools for teachers covers lesson planning, grading, and accessibility tools alongside the quiz platforms.
